UNIQUE MANUKA FACTOR UMF® is arguably the most trusted, easily understood and reliable standard for ensuring you are buying the best Manuka Honey.

The UMF grading system appraises natural markers found in Manuka honey, and assures purity & quality. To receive a UMF® grading, a honey must have the presence of DHA, MGO and leptosperin. This is compliant with the labelling guidelines published by the Ministry for Primary Industries.

The number of Manuka Honey is either a UMF® (Unique Manuka Factor) rating or a measure of the most important organic chemical contributing to the special antibacterial properties of Manuka Honey called Methylglyoxal – MG or MGO©.

UMF and MG are valid measures of the non-peroxidal activity unique to Manuka Honey. UMF measures the activity itself. MG or MGO© measures the compound responsible for a major component (but not all) of that activity. The MG number is much higher than the UMF number.

UMF® shows the relative effectiveness of Manuka Honey for inhibiting bacterial growth in direct comparison with the antiseptic phenol. The higher the UMF® number the greater the topical antibacterial effects.

The UMF® trademark is internationally verified. It guarantees authentic, unadulterated Manuka Honey. An independent laboratory determines the number. UMF® Honey must contain DHA (dihydroxyacetone), Leptosperin, and Methylglyoxal to be considered for rating.
